The vulnerabilities are caused due to errors when processing certain packets and can be exploited to e.g. interrupt existing sessions, stop an application from responding, or crash an application by sending specially crafted packets. The vulnerabilities are confirmed in DirectX 9.0c dpnet.dll version 5.03.2600.5512 on a fully patched Windows XP SP3 and version 5.03.3790.3959 on a fully patched Windows Server 2003 R2 Enterprise Edition SP2. Other versions may also be affected. SOLUTION: Host and play games using DirectPlay in trusted network environments only.
